To @ZZ whom tmoy concern:

Be it known that I, SAMUEL H. FANNING, a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in VMap-Cabinets, of which the following is a specification.`

This invention relates to improvements in cabinets for maps, charts, and the like, and has for one of its objects to provide a clevice of this character whereby a plurality of maps or charts may be rolled upon drums and any desired map or chart displayed.

Another object of the invention is to provide a device Vwhereby maps or'y charts are protected, while at the same time maintained in position for displaying. `With these and other objects in view, the invention consists in certain novel features of construction, as hereinafter shown and described and then specifically pointed out in the claims; and in the drawings illustrative of the preferred embodiment of the invention- FigureV 1 is a front view with the protecting apron partially raised. ,Y

Fig. 2 is a vertical section on the line- 2 2 of Fig. l.

Fig.V 3 is a rearY elevation with the back removed.

Fig. 4 is an enlarged perspective view of a portion of one of the idler carrier rollers illustrating the manner of constructing the tension device. Y

Fig. 5 is a detached perspective view of one of the pinion carrying studs of the winding drums. f

Fig. 6 is an enlarged sectional detail illus-` trating the manner of constructing the winding drum operating mechanism.

Fig. 7 represents enlarged perspective views of the supports for the winding drum operating mechanism with the parts separated. Y

Fig. 8 is a side elevation of rone of th winding drum y*operating gears. Y

Fig. 9 vis a detached perspective view of one of the drum kguard supporting brackets. Corresponding and Vlike parts are referred to in the following description and'indicated in all the views of the drawings by the same reference .characters v v The improved device may be supported upon a suitable base or stand, or attached toa wall as may be required, but for the-pur-VK forward edges of the end members11+12 pose of illustration is shown supported upon a suitablestand or'frame represented as a whole at 10. The improved device comprises a frame or casing including end mem-` bers 11-12, a top 13, a bottom 14, and detachable back comprising upper member 15, lower member 16, and an intermediate member l?, the member 17 being spaced from the confronting edges of the terminal members 15-16. The members 15-16-17 are secured to the casing members, preferably by screws, and arel designed to be removed only when the operating mechanism is in-v stalled or needs repairing.

The vacant space between the members 15-1.7 is occupied by a filler member 18, while the space between members 16-17 is occupied by detachable filler member 19. The members 18-19 are disposed opposite the map or chart kreceiving drums, to render thedrums and their operating mechanism accessible for changing the maps or charts or adding thereto when required.

The end members 11-12 are provided with guide channels or runways 20 to receive the ends of the Slat-s 21 of a slatted apron, the slats being glued or otherwise attached to a canvas or other fabric backing 22.

The terminal slats of the apron are larger than the remaining slats and are reduced at their ends to enable them to travel without 85 cramping over the upwardly curved por.- l tio-n 23 of the guideway. The lower termi-Y nal YSlat of the apron is provided with suitable hand grip devices 24, whereby the apron may be actuated.

It will be obviousby this arrangement that the front of the cabinet may be closed by drawing the apron downwardly and may be opened-by moving the apron upwardly, the slats traveling within the guideway.

Attached to the innerV faces of the end members l1-12 near their upper and lower ends are plates 24 each having a central bearing. The-plates 24 are located near the The bearings of the upper pair of plates receive studs 25 which support an upper y guide roller 26,Y while theV bearings vin the` lower plates receive studs 27 which support a lower 'gnide roller 28.YV The forward faces 'i105 of the rollers 26-28 are located slightlyY in the rear of the vapron dev-ice, asV shown in p Fig. 2, Bearing against each end of the' guide roller 26 and mounted loosely upon the studs 25 are guard washers 29, while. similar washers 30 bear against the ends oi Y the guide roller 2S and are loosely mounted upon the studs 27. A spring 31 is located between each of the washers 29 and the adjacent plate 2d, while similar springs 32. are located between washers 30 and the adjacent plates 2h the springs operating as tension devices to prevent the guide rollers from being rotated too easily.

Located beneath the upper plates 2a is a transverse supporting member while a similar supporting member 3d is located above the lower pla es 24. Extending between the terminal members 11-12 are a. plurality of transverse holding` members 35., spaced at uniform distances and arranged in vertical alinement with trie plates Bril-Sel. The members 33 Sil serve as supports for a plurality or' slats 36 spaced at uniform distances. or surface over which the maps and charts are moved and prevent lthe latter from being dellected intermediate the guide rollers.V

rllhe end slats or those next to the ends 11-12 ot the casing7 are relatively wide as shown in Fig. 3, and serve as guards between the yieldablc disks oi' the winding drums andV the fabric belt, as hereafter explained.

Attached to the inner face of the end member 12 intermediate the plates 2l which are attached to themember 12, are outer plates The plates 37 located adjacent to the guide rollers and 28, as shown in Fig. 3.

Spaced from each of the outer plates 37 is anl inner plate 38, the plates 37-38 being maintained in spaced relation by spacer blocks 89. rhe blocks 39 are provided with dowel pins d0 which extend through suit-V able apertures in the outer plates 3S. The plates 37--38 and the spacer members 39 are perforated to receive holding screws 41 by which the plates. and their spacer members are attached to the end member 12 of the casing. tain the spacer members in position and prevent them from rotating upon the screws.

Located between the plates 37-38 is a relatively large gear d2, the gear having a relatively large hub ad which extends fromy opposite sides thereof 'andengages inbearings in the plates 374438. The bore of the hub ed is square or otherwise than round to receive the correspondingly formed terminal 450i a crank ,46 which is extended through a suitable aperture in the end member 12.;

By this means the gear may be rotated from theI exterior of the casing. rlhe material which surrounds the crank aperture in the member 12 is protected by a metal sleeve 47.

rlwo sets of the plates V37438 together with the gear Ll2 are employed and located in vertical alinement and in spaced'relation,

The slats serve as a backgroundk The dowel pins operate,y to main-k as saown in Fig. 2,- and as the plates and their connections are precisely alike the description ot one will suliice for. both.-

pinion 4S is located between eaclrpair or' the plates 37e-88 and engages with the gears d2. Each of the pinions 48 is mounted for rotation upon a stud a9, the latter engaging in suitable bearings in the plates.

By this means it will be obvious that'when the crank 46 is applied to the hub ist of the gear Ll2 and rotated, motion will be transmitted at increased speed to the stud 49.

Attached to the end member 11 are plates 50 similar to the plates 37 but shorter land secured in place by screws or like devices. Each of the plates 50 is provided with a bearing to receive a stud 52 similar tothe studs 49. The studs are designed to support y winding drums 53, the drums being preferably wood and the studs pointed andthe points formed square or otherwise than round so that when driven into the drums they will beprevented from rotation therein. Bearing against the ends or the drums 53 are relatively large disks 5e, eachdisk being loosely mounted uponthe studs 49-52 Disposed between the disks 54: and the plates "38 and 50 are tension springs 54 which serve as brakes oir-tension devices to the drums to prevent them from rotating too easily.'` Attached to the drums 53 is a fabric sheet or belt 55, the latter being passed over theV guide rollers 26-28 and exthebelt and prevent outward displacement.

By this arrangement itwill beobvious that` when theV crank 46 is applied to the hub of the upper gear 4t2 and rotated in one n direction the Ifabric member 55` together with :the maps ory charts carried thereby will be wound upon the upperl drum 53 and unwound from the lower drum.

wound upon the lower drum and unwound Y Y l Then iiil the crank be transferred to the hub of the. lower gear and rotated, the fabric memberV togetherwith its mapsor charts will beVV Jfromv the upper drum. By'this means any. K

desired map or chart'whi'c'h" may y belocated upon the zt'abricV member will be exposed when'thel curtain device,r is elevated. Thev tension spring devices operate to holdthe guardV rollers and` the drums with suliicient force to preventlthe fabric member 55 Vand its attached maps or charts from working loose, but will retainv the'exposed map or chart strained condition.

ported at their ends by curved cleat devicesv 58, while the slats 57 are supported by similar curved cleats 59. The detachable rear member 1S is located opposite the upper drum and its operating mechanism, while the lower detachable member 19 is located opposite the lower drum and its operating mechanism, so that the drums and their` operating mechanismare readily accessible to enable the maps or charts tobe renewed or changed.

The maps or charts may thus be renewed er changed by simply removing one or both the members 18-19.

The confronting edges of the stationary back members 15-16 and 17 and the removable back members 18 and 19 are rab beted, as shown in Fig. 2, to assist in holding them in position.

Having thus described the invention, what is claimed as new is- 1. An apparatus of the class described comprising a casing including end members and open at the front., guide rollersv mount'-v ed for rotation in said end `members near the upper and lower portions of the casing, coacting winding drums mounted for rotation between said end members and having guard disks at the ends, a flexible element connected to said drums and leading' over said guide rollers and adapted .to contact with said disks, upper and lower transverse supports extending between said end members and between said rollers, and guard members connected respectively to said transverse supports and directed between said flexible element and said movable guard disks and preventing Contact of the flexible element therewith.

2. An apparatus of the class described, comprising a casing including end members and open at the front, guide rollers mounted for rotation in said end members near the upper and lower portions of the casing, coacting winding drums mounted for rotation between said end members, guard disks at the ends of the rollers and drums and rotative independently of the same, yieldable tension devices bearing against said disks, and a flexible element connected to said drums and leading over said guide rollers sov and adapted to contact with said yieldable disks and prevented thereby from displacement.
